As a case study, the town of Normal, Illinois, shows how a roof’s latitude, pitch, and azimuth can affect energy output.

A solar racking system’s strength is determined in part by the metal racking, but it also depends on the roof’s underlying structure. Rafters and any supporting structures must be strong enough to withstand your region’s maximum wind and snow loads.

In a sales environment where only one in 10 viable solar projects moves forward, getting from a good idea to a firm decision by a customer needs to happen fast. Here’s how one commercial solar installer makes technology work.

Multiple U.S. states require electric utilities to share their power grid data with solar developers. The resulting tools are like treasure maps for solar developers.

In sunny San Diego for Intersolar 2020, we’re seeing a new idea for tracking rooftop solar modules, diodes moving to cell level, two types of building-integrated solar products and some solar hot water.

Clean Power Research saw solar generation shift downward from the norm by as much as 10% in many locations across the United States in the first half of 2019.

New York state has chosen Zinc8’s zinc-air battery to demonstrate the technology’s viability over a three-year period in a 100 kW/1 MWh storage system.

A Department of Energy agency expects 17.4 GW (DC) of utility scale solar power generation capacity plus 6.6 GW of small scale PV will be installed in 2020. That volume would be 60% higher than the record, set in 2016.

Mercom Capital has released their annual report for 2019, describing the year as robust and showing company funding of $11.7 billion, up 20% over 2018, on top of announced project deals of $16.1 billion, up 14%.

Alencon’s silicon carbide-based String Power Optimizers and Transmitters enable the repowering of solar plants which need to replace 600 V inverters with newer 1,000 V or 1,500 V gear, or for project owners who wish to maximize electricity generation at aging and imperfect facilities with creative engineering techniques.
